TO ALL WHOM IT M AY CONCERN: v

Be it known that LFI-S. PESE, of Buifalo, in the county of Eric, and the State of `New York, have invented a new and useful Improved Blast Apparatus for Carburetters; and I dohereby declare'the following to be a full, clear, and exact description of the same, suieient to en'able others skilled in the art' to which it apprtains to construct and use 'the same, reference being had to the accompanying drawings, making part of this specification. l I Y l This improvement consists of a double bellows, (or a series of theun) operated through the medium of rods, by eccentrics one1 horizontal shaft, the eccentries being so arranged as to 'divide-the circle and opera-te the bellows consecutively, making an effective stroke in each direction as thevlower bellows are double with a partition, each' section hzwingconnection by a valve opening-upwards with the reservoir bellows above. i

n the drawings are shown three double lower bellows A, each `of the three having a partition, B, dividing it in fact into a pair ofbellows, the lower board C oscillating upon a horizontal axis or pivot, D, so that each' motion is made e`e`etive in delivering a body of air into the upper reservoir bellows E. 4

The motions 0i' the bellows are produced by eccentrics'F on the revolving shaft Gr,- the rods H connecting the eccentrieswith the bellows. The eccentrics are so arranged upon the shaft that they divide the circle, that is, when, as in the drawing, there are three of them; The ecccntrics are so set-upon the shaft that they follow in regular consecutive series, and operate upon thebellows to produce a constant blast.

The sides or expanding and contracting portions ofthe bellows nrernade of wooden plates, united to each other and to the upper and lower boards by means of elastic membranes or strips, so'that they will not bag out when a blast is applied but will bear considerable pressure. Cranlis may be substituted for the eecentrics, and the shaft may have a reciprocating rotary mot-ion or a complete revolving motion.

Having described my invention, what I`claimas new, and desire to secure by-*Letters Patent, is-

1.. The double bellows A, so constructed that the sections are reciprocallyzoperated by the vsame impulse from cra-nk or eccentric on a rotary or vibrating shaft, substantially as described.

2. The combination of the rotary or vibrating shaft G, provided with cranks or ecc-entries, the connectingrods H, and series 0f double bellows A A, substantiallyas described. l 4,

To lthe above specification of my improvement I have signed my hand this 19th day ofMarch, 1867.
